Lesson: The Ideal Gas Law in terms of Number of Moles Physics
In this lesson, we will learn how to calculate the relationship between the number of moles in an ideal gas and the values of its bulk properties.
A cloud of gas has a pressure of 220 kPa and a temperature of 440 K. The gas contains 8.2 moles of a particle with a molar mass of 10.5 g/mol. Find the volume of the cloud. Use 8.31 m2⋅kg/s2⋅K⋅mol for the value of the molar gas constant. Give your answer to two decimal places.
A gas consisting of 25.6 moles of carbon fills a volume of 0.128 m3 and has a pressure of 135 kPa. Find the temperature of the gas. Use a value of 12.0107 g/mol for the molar mass of carbon and 8.31 m2⋅kg/s2⋅K⋅mol for the value of the molar gas constant. Give your answer to the nearest kelvin.
A gas cylinder with a volume of 0.245 m3 contains a gas at a temperature of 350 K and a pressure of 120 kPa. Find the number of moles of the gas particles in the cylinder. Use 8.31 m2⋅kg/s2⋅K⋅mol for the value of the molar gas constant. Give your answer to one decimal place.
